Even something like Homebrew for the platform would go a long way. The tag exists, but platform would probably help visibility more.
There are all sorts of consoles and retro PCs with homebrew ROMS on itch.io, but they aren't always easy to find.
Viewing post in Alwa's Awakening The 8-Bit Edition comments
Homebrew would be too broad in my opinion. a subsection called 'Vintage Systems' that you could expand to all the old PCs, and Game consoles.
tags are so often abused here. lost count how many 'Mega Drive' and 'NES ROM' games i've come across that have NOTHING to do with Mega Drive/Genesis/NES. then on the other side of that coin... i only found Mega Man: The Sequel Wars because someone i follow added it to their collection. criminal to miss that one.
anywho, i played Alwa's Awakening (8-bit) last night, and my save from the demo was there! guess since both ROMS are named the same my Everdrive loaded the save for it. *note i didn't load it. started anew so i can't confirm it works or not.
cheers
